SHA1 can be used to calculate a checksum to verify that a 'message' has not been altered. Unlike 
<a href="usecrc32fingerprint.html">CRC32</a> it is nearly impossible to modify the original message and still 
produce the same SHA1 fingerprint. 
<br>
<br>
Here is a quick explanation taken from the RFC 3174 on SHA1: 
<br>
<br>
'The SHA-1 is called secure because it is computationally infeasible 
to find a message which corresponds to a given message digest, or to 
find two different messages which produce the same message digest. 
Any change to a message in transit will, with very high probability, 
result in a different message digest, and the signature will fail to 
verify.' 
<br>
<br>
More information can be found in the RFC 3174: 
<a href="http://www.ietf.org/rfc/rfc3174.txt">http://www.ietf.org/rfc/rfc3174.txt</a>.
